VEHICLE-LAMP.

Specification of Letters Patent.

. Application tiled December 1, 1911.

Patented Feb. 25, 1913.

Serial No. 663,892.

To all whom it may concern Be it known that I, JOSEPH E. ALLEN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvementsv in Vehicle- Lamps, of which the following is a. specitication.

My invention relates to improvements in vehicle lamps and more specifically to elec trically lighted lamps of this character which are designed especially t'or use as headlights.

The object of my invention is the production of a vehicle lamp of the character mentioned, which will be of durable and economical construction and of high etticiency in use.

Other objects will appear hereinafter.

lViththese objects in view my invention consists in the construction and arrangements of parts hereinafter described and claimed.

My invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which,

Figure l is a central section ot a vehicle lamp embodying in v invention. l"ig. 2. is a detail perspective ot' a t'raginent ot the lamp showing the means ot' securing the glass fastening channel ring upon thc body of the lamp, andV Fig. 23 is a sectional dctail taken on substantially line 1c .r ot' Fig. 1.

rlhe preferred forni ot' construction as i illustrated in the.drawingsconi'piises a body l which is formed ot' metal. said body being spun troni a single piece ot material into substantially parabolic conformation shown. .v\rranged at the apex or rearward end of the body l is a socket which is in screw-threaded connection with a nipple il provided for thc reception thereot' upon said body, the adjacent portion-of the latter being provided with an opening to permit of the passage ot said socket, as clearly shown in Fig. l. Mounted in the socket L is a plug 4: of an ordinary electrical lamp. 4 indicating the globe thereof. said plug being frictionally held in said socket so as to permit of ready detachment thereot' it de- Sil'ed. The rearward-side of the socket 2 is perforated in order to permit. of tht` passage. ot the conductor wires which lead to orly and being knurled for manual engagement to ett'ect such rotation of Said plug. This adjustment which is atorded the electric light evidently provides means for fo ciising the lamp which is of great advantave as will be appreciated ythose skilled in th art.

The front or month/end of the body il is i closed by a suitable transparent closure 5 preferably tormed of glass, said closure being securely held 1n position by mean's of a split channel ring 6 which engages the pe-.

riphery of said closure and a circumferential tiange 7 formed at the mouth of the body l. The ends of the rings t3 are' provided with lugs 8 which are connected by a screw 8. the latter evidently atfoi'ding means of tightening the securing ring to opera tive. position.

The mouth portion of the lamp adjacent the flange i' is otl'set outwardly and cylindricalty toi-ined as shown to lend strength and durability to the construction. it being clear that' with this const ut-tion annular shoulders are formed at the mouth of the lamirbody which will prevent ready beiiding or distortion. lso. with this construction a surface is presented to which support-engaging sockets tl inav lic secured. The support-cugaging sockets tl are arranged at opposite sides otl thc lamp. the `sawmtlbcmg secured in position prct'crably b v means-ot' rivets l0.

The lamp ot the construction above ,sot ihortli is diii'ablc and c \'trcmc| .simple und economical so that thc .saine may bc mai-iiit'acturcd at an exceedingly low cost. 'the lamp is otl tical and tinishcd appcaranct` and because ot' the l'ocal adjustment atl'orded is highly etlicient in usc. l`hc t'ocal adjustment as will be observed ma)Y bc cllcctcd l'roni the exterior ot' the lamp. it being nnncccssanv to open thc body` thatv is. to rcmove the closure 5.

ln thtl operation ot` the lanip.then, it will be obscrvcd that it is unnecessary to enter the interior of thc lamp. Thisbeing so after the interior ot' the lanip axid ot the glass have been once cleaned and the glass secured in position, the saine will remain in tJO handy; :L hlfouded nipple arranged ceurzdy at ih@ um? of Said body; a soke threaded in said nipple; and an electric liofht bulb having a plug fricionally tiing sind socket membe, substantially as described.

A. amp compiising :1 Asubstantiamfdy parabolic body open at its front side; a runspmfent covering for the front of said body; a lx'eaded 'hippie arrangedt the Nmof smid bodj; a socket member threaded in sniff nippe and provided Wih an end pinze hm g an opening in its ouer end to permit Uw, pzlssage of mires; and an eecligh; uub having a pug frctonaly 'i'.ug said sncie; member, substancaly as (iwal-ibo@ l n lesmony hereof I hav@ signed my mme to fKxS.
